husky sensitive stomach, weight, nails

Question
I have a 4 1/2 month old Siberian Female.  We had problems with her having loose stools to diarrhea for awhile but finally found a food that has been fine with her stomach.  (Innova Evo- high protein diet).  We were told by two friends who both own siberians that they have sensitive stomachs, is that true?  also, my sibe tends to drink water until she coughs or throws it up sometimes.  Most of the time she just sits by it and rests her head on the bowl.  One friend who owns a sibe said that their husky drinks tons of water as well which caused him to have diarrhea so they try not to let him have tons of water all the time.  is this also a husky thing?  

the next question is about a friend's male sibe.  He is about 2 years old and was purchased from a pet store.  He is extremely thin and they cannot seem to get any weight on him.  They're starting to try higher protein food and wet food to see if it will help but do you have any other suggestions like maybe feeding him puppy food to gain some weight?

last question, what is a method that you recommend with trimming their nails?  When we got our puppy's nails trimmed at the vet she screamed bloody murder and our friend's husky peed in fear and would not let them near his feet.  I also took care of a sibe female at a boarding facility and she had to be muzzled when doing her nails (overall though she was perfect).  any suggestions?

Answer
Huskies can have sensitive stomachs.  Sometimes, feeding raw meat can actually help and is worth trying.  As for the water thing, not something I had heard of before, but being a thick coated breed, they can definitely be thirsty pups.

As for your friend's male sibe, feeding higher protein/fat food (or possibly puppy food that meets that requirement) can definitely work.  Adding some meat to the diet may help as well.  I see no issues in doing either if the dog is below weight.

Nail trimming - tough . . . but muzzling is a good option, and the best thing is conditioning the dog to it.  Giving treats, massaging the dog's paws, and just getting the dog used to the nails and paws being handled is beneficial.  It takes time, but over time, it can be done.
